设计了一款应用在柴油机上的电控EGR系统,并进行了不同EGR率对柴油机经济性的影响研究和稳态十三工况下的排放性研究。试验结果表明：采用电控EGR技术后,试验柴油机比油耗在不同工况下有不同程度的升高,尤其在高负荷区域内;NOx排放有着较为明显的下降,微粒有一定程度的升高,HC排放总体上变化不大。

We design an electronic control EGR system using in diesel engine,and influence of different EGR rate on engine economy and emission is done.The results shows：using electronically controlled EGR technology,for the test engine,the fuel consumption rises at different degrees,especially in high load areas;NOx emissions have a more significant decline;particles increase to a certain extent;HC emissions have little change.
